Carbon paper holder



Filed April 28. 1930 Patented Mar. 22, 1932 PATENT OFFICE CHARLES L.KELLY, OF CHICAGO, ILLINOIS, ASSIGNOR TO CONTINENTAL CARBON CORPORATION,OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS CARBON PAPER HOLDERApplication filed April 28,

The present invention relates to carbon paper holders, and more inparticular to the provision of a novel construction adapted for use intypewriters and similar machines. The construction disclosed in thisapplication is an improvement upon that shown in my Patent No.1,743,820, granted January 14, 1930.

In constructions of carbon paper holders, prior to that of my patent andthe present application, the carbon paper was secured to the backingstrip and no provision was made for detaching the carbon sheets, nor wasany provision made for the addition or subtraction of the number ofsheets with which the holder was provided. In such rior constructions,the backing strip and caron sheets, when once assembled, became apermanent structure, and when the carbon was no longer of use, or whenthe attaching means became broken or disengaged, the entire holder wasnecessarily discarded.

Among the objects of the present invention are to provide a carbon paperholder for receiving a plurality of pieces of carbon paper intermediateof which are placed sheets of letter paper, the holder being soconstructed that the entire assembly may be readily and easily insertedinto a typewriter or similar machine.

A further object of the invention is to provide a novel construction ofbacking sheet for a carbon paper holder, the same being provided at itsupper end with a folded portion formed' integral with the backing sheet,the fold providing a means for intercepting and alining an edge of thecarbon paper. By reason of the integral construction of the backingsheet and the folded portion, no difficulty is encountered in feedingthe holder with its retained sheets into a proper position in thetypewriting machine.

A still further object of the invention is to provide a carbon paperwhich has suitably spaced openings adapted to be alined with 1930.Serial No. 447,856.

similarly spaced openings in the backing sheet and the folded strip.Another object is to provide a novel construction of interlacing memberformed of a flexible material and provided at its end with a rounded tipportion, the central portion thereof being formed of a greater widththan the remaining portion. This flexible interlacing member is soconstructed that the ends thereof may be entered and interlaced throughthe central aligned openings in the front or folded strip, carbon andbacking sheet, the ends then being adapted to be interlaced or interceted in the openings adjacent the opposite e ges of the folded portion,carbon and backing sheet. This detachable interlacing member not onlyprovides means for assembling the folded portion, carbon and backingsheet, but it also provides an abutment for the letter paper that is tobe inserted in the carbon paper holder. The enlarged centralportion ofthe interlacing member also prevents any lateral shifting ordisplacement-thereof when the parts have been placed in assembledrelation.

Referring more particularly to the disclosure in the drawings, theassembled carbon paper holder is designated generally as 1, and includesa backing sheet 2, having its upper end folded to provide a top strip 3.Intermediate the top strip and backing sheet is provided carbon paper 4.The carbon paper when inserted intermediate the top strip and backingsheet, strikes o-r abuts against the fold and is thereby properlypositioned. This backing sheet is ordinarily constructed of heaviercomposition than the ordinary paper and may consist of oil paper orother suitable and desirable material, and is generally of the samewidth as the carbon sheets so as to facilitate the assembly of thecarbon and backing member. A plurality of suitably spaced openings 5 and5 are provided in the upper strip 3, carbons 4 and backing sheet 2.These openings are of a substantial width and the openings in the upperstrip, carbons and backing sheet are equally spaced so that theseopenings may be placed in alinement for the insertion of an interlacingmember.

The top strip 3, carbons and backing sheet are held together by means ofa flexible interlacing member 6. This member may be constructed of anysuitable flexible material,

such as celluloid or other material having the characteristics thereof.The end portions 7 of the interlacing member are rounded so as tofacilitate their insertion through the alined openings in the top strip,carbons and backing sheet. Intermediate of the end portions, is provideda portion 8 of substantially greater width which provides a grippingmeans when the interlacing member is bent and inserted through thealined openings 5, the ends 7, 7 being inserted initially through thecentral openings 5 and from there to the openings 5 adjacent the edgesof the carbon holder.

Further objects are to provide a novel construction of maximumsimplicity, etliciency, economy and ease of assembly and operation andsuch further objects, advantages and capabilities as will later morefully appear and are inherently possessed thereby.

The invention further resides in the combination, construction andarrangements of parts illustrated in the accompanying drawings, andwhile I have shown therein a preferred embodiment, it is to beunderstood that the same is susceptible of modification and change,without departing from the spirit of my invention.

In the drawings:

Fig. 1 is a plan view of the carbon paper holder.

Fig. 2 is a view in vertical cross section taken on the line 22 of Fig.1, the sheets of writing paper having been removed.

Fig. 3 is a fragmentary view of the backing sheet and the integral topstrip which is folded over the sheet.

Fig. 4 is a view in horizontal cross section of the holder taken on theline 4-l of Fig. 1, and showing the means of assembling the backingsheet, top strip and the carbon paper.

Fig. 5 is a fragmentary view in rear elevation of the assembled holder.showing clearly the end of the interlacing member in position.

Fig. 6 is a. view in perspective of the interlacing member.

After the interlacing member has been placed in position, the same canonly be removed by the operator grasping the widened portion 8 andpulling the member from the holder. W'hen assembled, the interlacingmember cannot be shifted laterally since the widened portion 8 is of alength substantially the distance between the central openings in thecarbon paper holder.

The letter paper 9 is inserted between the sheets of carbon paper untilthe same abut against the lower edge 10 of the interlacing member. Thisedge 10 provides an abutment and means for alining the letter paper inthe holder. Any number of sheets of writing pa- -per may be inserted,depending upon the number of sheets of carbon paper that are detachablyheld in the carbon paper holder. By reason of this construction, thestenographer can arrange the desired number of carbon papers in theholder in the morning, and will not have to change the same throughoutthe day for any letters requiring the same number of carbons. If it isdesired to prepare a less or greater number of carbons, any carbonpapers may be subtracted or added to the number in the holder. It is asimple matter for anyone to remove the interlacing member and to changethe number of carbon sheets in the holder.

By reason of the unique construction of the holder the assembly may beeasily insertcd into the typewriter or similar machine, and there is nodanger of the assembly becoming disengaged. Also, by reason of theconstruction, the parts may be readily alined and kept in suchalinement.

From the above description and disclosure, it will be readily seen thatI have provided a construction having the advantage of cheapness andsimplicity, one which is highly efiicient, may be readily assembled anddisassembled, and one which will give a maximum period of use.

Having thus disclosed my invention, I claim:

1. A carbon sheet holder comprising a backing sheet for a plurality ofremovable superposed carbon sheets, an edge of said backing sheet beingfolded upon itself to provide means for intercepting and aligning anedge of said carbon sheets, a flexible member arranged transversely ofsaid backing sheet and having a removably interlaced engagement withsaid folded portion, carbon sheets and backing sheet so that the holdermay be readily inserted in a typewriting machine, and positioning andaligning means on said member for preventing lateral shifting of themember in its interlaced engagement.

2. A carbon sheet holder comprising a backing sheet for a plurality ofsuperposed carbon sheets, an edge of said backing sheet being foldedupon itself to provide means for intercepting and aligning an edge ofsaid carbon sheets, and a flexible member arranged transversely of saidbacking sheet and having a removably interlaced en agement with saidfolded portion, carbon slieets and backing sheet so that the holder maybe readily inserted in a typewriting machine, said member being providedwith an enlarged central portion for properly aligning and positioningthe same in interlaced engagement and for preventing lateral shiftingthereof after the holder has been assembled.

3. A carbon sheet holder comprising a backing sheet for a lurality ofsuper osed carbon sheets, an e ge of said sheet ing folded upon itselffor the reception and alignment of said carbon sheets, said backingsheet, folded portion and carbon sheets being provided with suitablyspaced and ali ed openings, a detachable interlacing inem r ada ted tobe passed through said 0 enings or holding said backing sheet, fol edportion and carbon sheets in assembled relation, and a projection onsaid member for roperly positioning the same in its interlac engagement.

In witness whereof, I hereunto subscribe my name to this s ecification.
